摘要： A mechanism is provided with a slide adjustment member that is mounted on a frame supporting a carriage assembly of a printer. The carriage assembly is pivotally mounted upon a support shaft carried by a frame. The slide adjustment member has indexing teeth that engage with a plurality of saw-tooth detents. The sawtooth detents are longitudinally disposed upon a surface that is at a slight angle in the range between 3 and 4 degrees, and preferably about 3.44 degrees with respect to the horizontal. Horizontal movement of the slide member over this angled surface causes the carriage assembly to pivot about the support shaft. In so pivoting, the printhead carried upon the carriage assembly is forced to move with respect to the platen, thus changing the paper thickness gap therebetween. Each indexed movement of the slide member past a detent tooth provides a change of 0.003 inches in the gap. This change is equivalent to the difference between single and double ply paper. Thus, the invention provides a simple, low cost slide member and sawtooth index surface for changing the paper gap between the printhead and platen.
摘要翻译：设置有安装在支撑打印机的托架组件的框架上的滑动调节构件的机构。托架组件枢转地安装在由框架承载的支撑轴上。滑动调节构件具有与多个锯齿形棘爪啮合的分度齿。锯齿状棘爪纵向地设置在相对于水平面处于3至4度之间，优选为约3.44度的范围内的微小角度的表面上。滑动构件在该成角度的表面上的水平移动导致托架组件围绕支撑轴枢转。在这样的枢转中，承载在托架组件上的打印头被迫相对于压板移动，从而改变其间的纸张厚度间隙。滑动构件经过止动齿的每个分度运动在间隙中提供0.003英寸的变化。这种变化相当于单层和双层纸之间的差异。因此，本发明提供了一种简单，低成本的滑动构件和锯齿形折痕表面，用于改变打印头和压板之间的纸间隙。

摘要： A new paper loading system is featured with a convenient drop-in paper loading and a full slip path in a receipt printer. The paper is dropped into a paper receiving bucket disposed in the central portion of the printer. The paper is fed from the bucket; and thereafter, a receipt is printed. Then, the paper is cut to the appropriate receipt length. A slip path is also provided for insertion of a single or multi-part form used for credit or check validation. The relative position of the slip path would normally interfere with the drop-in loading of the paper supply roll into the bucket. The system allows the fixed blade assembly to support a slip path upon a rear surface thereof. The slip path is substantially parallel or adjacent to the paper receipt path, which passes between assemblies supporting a fixed blade and a movable, rotary blade. The fixed blade unlatches and pivots away from the rotary blade, thus opening the printer and exposing the paper loading bucket for access thereto. The design eliminates the previous interference of the paper path with the slip path.

摘要： The present invention features a photosensing mechanism for a receipt-printing machine which senses a low condition of a paper supply roll housed within a bucket of the receipt-printing machine. The paper-supply roll has a "floating" characteristic; that is, no fixed rotational mounts align the roll within its feed bucket. The photosensing mechanism adjusts to different supply-roll positions within the feed bucket, the different positions of which result from different mounting orientations of the receipt-printing machine.

摘要： The present invention features a receipt printing and check validating machine. The machine is characterized by a drop-in loading for the receipt paper supply roll. A first drive roller for the receipt printer is pivotably mounted in a clamshell bucket. The first drive roller is swung into contact, when the clamshell bucket is closed, with an idler roller centrally mounted on a fixedly-mounted idler/drive combination shaft. The check validating drive features a second, slip drive roller pair that is in pivotable contact with a pair of slip drive rollers mounted on the aforementioned fixedly-mounted idler/drive combination shaft, one on either side of the receipt idler roller. Thus, the idler/drive combination roller shaft has a fixed position with respect to both drive rollers, and is used cooperatively by both drive rollers. Both the check and the receipt can emerge from the same slot in the housing of the machine.

摘要： The present invention features a method and a fixture for determining the asymmetrical character of a readhead prior to its installation in a check-validation machine. Such a machine that is used to validate checks uses a stepper motor drive to convey the check past the readhead. The magnetic field produced by the coil of the stepper motor interferes with the capability of the readhead to recognize the magnetic indicia on the check. Once determined, the asymmetrical sensitivity of the readhead towards the magnetic flux allows the manufacturer to mount the readhead with its sensitive side away from the stepping motor of the validating unit. The readhead asymmetry is determined by the method of this invention by measuring an output voltage pulse of the readhead, when it is excited by magnetic pulses both forward and rear of its read gap. The excitation is provided approximately one inch from the read gap. The exciting pulses are of similar magnitude and timing as that of the signal field generated by the slip drive of the stepper motor. The peaks of the forward and rear output pulses are converted into DC voltage levels, which are then fed into a comparator circuit. The comparator circuit controls the lighting of a "go/no go" indicator LED, which tells the operator which side of the readhead is more sensitive to the magnetic flux.
摘要翻译：本发明的特征在于一种用于确定读取头在其安装在检验验证机中之前的不对称特性的方法和夹具。用于验证检查的这种机器使用步进电机驱动器将支票传送通过读取头。由步进电机的线圈产生的磁场干扰了读取头在支票上识别磁性标记的能力。一旦确定，读取头对磁通量的非对称灵敏度允许制造商将其读出头安装在其敏感侧远离验证单元的步进电机。通过本发明的方法通过测量读取头的输出电压脉冲，当其被读取间隙的前后的磁脉冲激发时，读取头不对称性是确定的。从读取间隙提供约1英寸的激发。激励脉冲具有与步进电机的滑动驱动产生的信号场相同的幅度和时序。正向和反向输出脉冲的峰值被转换成直流电压电平，然后馈送到比较器电路。比较器电路控制“去/不走”指示灯的点亮，这告诉操作者读头的哪一侧对磁通量更敏感。

摘要： The present invention features an apparatus for a journal-receipt printing machine. The apparatus semi-automatically loads the journal paper onto the take-up spool. The machine also has a drop-in, loading capability for the journal-paper supply-roll. The journal-printing apparatus utilizes a duckbill, take-up core or spool that is bifurcated into stationary and movable sections. The bifurcated spool is spring-loaded, and is caused to bias-close through the movement on the cam surface. The leader of the journal paper is placed over the stationary section of the spool. The gear train causes the cam follower to turn over the cam surface and close. The gear train then forces the duckbill spool shut against its biasing, thus capturing the paper between the spool sections. In this fashion, the procedure of resupplying the machine with journal paper is accomplished without the user having to thread paper. A pair of rollers positioned within the spool allows the captured leader of the journal paper to be easily removed from the closed spool.

摘要： The present invention features a cutting mechanism for a receipt-printing machine, which has paper dispensed from a paper-supply roll. The cutting mechanism has a "v"-shaped, guillotine blade that is held in a blade holder. The blade is driven via the blade holder against a stationary blade and into cutting contact with a paper web containing receipt indicia. The paper web is dispensed from a paper-supply roll located within the printer. A displaceable cover is provided to allow for convenient paper loading and, occasionally, paper jam clearing. There is a blade guide which has side mountings for guiding at least one end tab of the guillotine blade into perpendicular contact with the paper web. The guillotine blade is driven through the blade guide into cutting contact with the paper by a drive cam. The drive cam rotatively engages the blade holder, providing the blade with a forward thrust. The cam is driven by a motor-driven gear train that has a timing gear. The rotating timing gear activates a switch after every complete rotation, which terminates power to the motor, thus allowing a single rotation for the drive cam and, hence, a single cutting cycle. The guillotine retracts from the blade guide under the influence of spring biasing, and is then ready for the next cutting cycle. The guillotine blade is retracted to a remote position within the printer.
摘要翻译：本发明的特征在于一种用于收据打印机的切割机构，其具有从供纸辊分配的纸张。切割机构具有保持在刀片保持器中的“v”形的闸刀。刀片通过刀片保持器驱动抵靠固定刀片，并与包含收据标记的纸幅切割接触。纸幅从位于打印机内的供纸辊分配。提供可移动的盖子，以便于纸张装载方便，偶尔也会卡纸清除。有一个叶片引导件，它具有用于引导闸刀叶片的至少一个端部突片与纸幅垂直接触的侧面安装件。断头刀片通过刀片引导件被驱动凸轮与纸张切割接触。驱动凸轮可旋转地接合刀片保持器，为刀片提供向前的推力。凸轮由具有正时齿轮的电动齿轮系驱动。旋转正时齿轮在每次完整的旋转之后启动一个开关，从而终止电动机的动力，从而允许驱动凸轮单次旋转，从而允许单个切削循环。在弹簧偏置的影响下，闸刀从叶片引导件缩回，然后准备好进行下一个切割循环。断头台刀片缩回到打印机内的远程位置。
