摘要： PROBLEM TO BE SOLVED: To integrate the operation of VTR with digital satellite broadcast receiver (IRD) and to improve operability by performing communication so that the VTR and the IRD can set or acquire mutually operating state or set contents. SOLUTION: A VTR 100 and the IRD are connected through connecting terminals 271 and 272 by a communication line 270. When the channel-up button of remote controller 260 is pressed, for example, while the contact of input changeover switch 13 is connected to a side A, a VTR system control circuit 20 retrieves the channel number of analog broadcasting to be next tuned and controls the tuning of analog broadcasting reception tuner 12 to the retrieved channel. While the contact of input changeover switch 13 is connected to a side B, the VTR system control circuit 20 transmits the request of channel-up to the IRD. An IRD system control circuit 220 receives the request, retrieves the channel number of digital broadcasting to be next tuned and controls the tuning of digital broadcasting tuner 202.

摘要： PURPOSE:To handle and issue any kind of ticket by enabling a ticket to be sucked from the outside of a housing at a request to issue the ticket different from tickets set in the housing. CONSTITUTION:Characteristic information can be set in a hopper part 35 and when a ticket request queue arrives at a terminal control unit 2 from a host computer 1, the terminal control unit 2 issues a command for confirming state information to a ticket issuing device 3. In response to it, the ticket issuing device 3 sends information including 'setting information' in the hopper to a terminal control part 23, and the terminal control unit 2 compares this 'setting information' with 'ticket kind information' in a message received from the host computer 1 by a calculation part 22, automatically decides whether a ticket issuing process is completed by feeding from the hopper or form suction from an inserter from the terminal control part 23 to a mechanism part 36 on the basis of the comparison result, and issues a process command for the decided process, thus advancing the processes.

摘要： PURPOSE:To provide an optical disk device capable of stabilizing a laser output and detecting an abnormality thereof. CONSTITUTION:One photodetecting element 41 out of bi-sected photodetectors 4, is used for stabilizing a laser output, and another photodetecting element 42 is used for detecting the abnormality of a laser output. The output of the photodetecting element 41 is led to an automatic power control circuit 11, and inputted into a laser driver 10 to generate a certain low output power at the time of reproducing. The output of the photodetecting element 42 is led to an abnormality detection circuit 12 to detect the abnormality of a laser output. When the abnormality occurs, a laser emission is stopped by controlling a laser driving current through the laser driver 10.

摘要： PURPOSE:To reduce the control processing accompanied by the detection of the exhaustion of paper control unit. CONSTITUTION:In a printer 1, the printing of the length corresponding to that of a page is applied to the page at each time when the indicated length of the page is transmitted from a host device and, at the point of time when the printing to the page is completed, a page end position printing completion signal is generated from a page end position printing completion detection part 8. When a paper exhaustion detection signal is outputted from a paper end detection sensor 5, the paper exhaustion detection signal is transmitted to the host device from a paper exhaustion detection signal output control part 7 for the first time at the point of time when the first page end position printing completion signal is generated and, on the basis of said detection signal, the printing completion control of the printer is directly taken by the host device.

摘要： PURPOSE:To make it possible to suppress offset of tracking error signal produced at the time of positional correction of light spot by shifting the departing position of light flux from a prism simultaneously with variation of deflecting angle thereof through rotation of a wedge type prism. CONSTITUTION:A wedge type prism 140 is provided with an actuator 141 for rotating the prism 140 around Z axis on the drawing (normal to the surface of paper). Both first and second light spots 162, 172 are subjected to positional control for the distortion component of an optical disc 1 through positional control of an objective lens 110. Relative positional shift of two light spots, caused by adjustment or temperature, is corrected by feeding tracking error signals obtained from a second optical detector 127 and a subtracking error detecting circuit 7 back to the actuator 141 and rotating the prism 140 thereby varying the deflection angle of light flux 170 impinging on the lens 110.

摘要： PURPOSE:To obtain a simple and reliable mechanism by utilizing the action of a loader mechanism which conveys a cartridge so that a new driving source is not added. CONSTITUTION:When the disk cartridge 1 is inserted in the loader 2, a cartridge shutter 4 is opened by the arm 3 of the loader 2. By inserting the cartridge 1 more, the cartridge 1 butts on the end surface 5 of the loader 2 and the loader 2 starts to move. The loader 2 moves along the L-shaped guiding groove 7 of a loader base 6 and the cartridge 1 gets on loader pins 8 and 8' which are positional reference and stops at the end C of the guiding groove 7. In such a state, the reference surface 12 of an electromagnet 9 comes into contact with the upper end surface 15 of the loader 2 and stops, then the projecting part 14 of a magnet arm 13 becomes in non-contact state with the upper end surface 15 of the loader 2. An optical disk 16 is set on the hub 18 of a spindle motor 17 and starts to rotate. The optical disk 16 and the electromagnet 9 face without contacting with each other and when electricity is applied to the electromagnet 9 a fixed quantity of magnetic field is generated on the recording surface of the optical disk 16 so as to perform the erasion and rewriting of data.
