摘要： PURPOSE:To automatically open and close a bail roller without using an expensive part by meshing a pinion with an outer gear when the bail roller is closed and meshing the same with an inner gear when the bail roller is closed and meshing the same with an inner gear when the bail roller is opened and controlling the meshing of a clutch gear and a bail timing gear. CONSTITUTION:A bail roller 5 is present at the closed position being in close contact with a platen 6 and a clutch gear 2 is meshed with a bail timing gear 3a to operate a gear train and the platen 6 feeding paper is rotated in a counterclockwise direction and the rotation of the platen 6 is transmitted to a bail arm 4b through the bail timing gear 3a, an outer gear 3b and a pinion 4a and the bail arm 4b is revolved in the clockwise direction and the bail roller 5 moves in an opening direction. The outer gear 3b rotates the pinion 4a by the quantity corresponding to the number of teeth to revolve the bail arm 4b to stop the same. The pinion 4a is detached from the meshing with the outer gear 3b to be meshed with an inner gear 3c. The rotation of the platen 6 is transmitted to the bail arm 4b and the bail roller 5 moves in a closing direction with respect to the platen 6.

摘要： PURPOSE:To automatically perform the separation and contact of a paper bail with respect to a platen without taking space by driving a paper bail support plate by the power of a motor to carry out the separation and contact of the paper bail with respect to the platen. CONSTITUTION:When a ribbon motor 1 is rotated to the left, a ribbon drive wheel 3 is rotated to the right while an intermediate gear 8 and a paper bail driving gear 9 are rotated to the left. At this time, a support plate 6 receives rightward rotary moment to move and the driving gear 9 is meshed with a gear 12a. By this mechanism, since the gear 12a is rotated to the right and a plate 12 moves a plate 13 in the direction of a platen 15, the extension part 14e of a paper bail support plate 14 is pressed toward the platen 15 and the support plate 14 is rotated to the left against the spring force of a paper pressing spring 14b and a paper bail 14a is separated from the platen 15. When the motor 1 is rotated to the right, the support plate 6 receives leftward rotary moment to move and the driving gear 9 is separated from the gear 12a. Therefore, the support plate 14 is rotated to the right by the spring force of the paper pressing spring 14b and the paper bail 14 comes into contact with the platen 15.

摘要： PURPOSE:To automatically open and close a bail roller by mounting a drive gear having a partial gear part, a bail arm having a gear part having a tooth form over the entire periphery thereof and holding the bail roller at the leading end part thereof and an idle gear meshed with the partial gear part. CONSTITUTION:A platen gear 2 and the gear part 6a provided to the root part of a bail arm 6 holding a bail roller 7 at its leading end part are connected by a gear train constituted of the clutch gear 3 having the tooth form meshed with the platen gear 2 on the outer periphery thereof, a drive gear 4 having a gear part 4a which has the tooth form meshed with the clutch gear 3 on the entire periphery thereof and a partial gear part 4b having a partial tooth form integrally rotating along with the gear part 4a and the idle gear 5 meshed with the partial gear part 4a when the partial gear part 4b is not meshed with the gear part 6a of the bail arm 6.

摘要： PURPOSE:To obtain a maximum paper from introducing port in a restricted space by including a center guide, in which a bail shaft is mounted, and a guide roller which is rotated with a paper from while retaining it with a guide center eccentrically placed relating to the center of the bail shaft. CONSTITUTION:An eccentric roller 21 determines a fitting position in a groove of a mounted bail shaft 22, while the roller 21 is constituted by including a center guide 11 of a guide center (b) with the center having the periphery eccentrically placed from a shaft center (a) of the shaft 22, and a guide roller 12 fitted with the periphery of the guide 11 as a guide and rotated in the case of feeding a paper form. The above-mentioned eccentric roller 21 is used for a paper form retaining roller, used for a printer, to insert a paper form 32 between the roller 21 and a platen 31, and small and large thickness parts are respectively provided in a side, restricted with a space by a cover 33, and a side for introducing the paper form.
