Title: Page turning-over apparatus
Inventor: NAKAMURA HIROKATSU
IPC: B42D9/04
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components for turning over a page by clamping a medium at a position retracting from a conveying passage and a position protruding to the passage, and driving to control a retaining roller, movable guide and clamping means. SOLUTION: Since a conveying passage is opened and a pinch roller 8 is urged to a turning-over roller 7, a bankbook PB is conveyed in a right direction by the roller 7. Thus, a jumped-up page is turned over. And, the bankbook PB is discharged to an insertion port at the time of this operation. In this manner, since an end of the bankbook PB is clamped by a clamping mechanism, it can be turned over and conveyed by the roller 7. Accordingly, the turning-over and conveying can be executed by one conveying motor 5. Since the end of the bankbook PB is clamped by the clamping mechanism protruding to the passage, it can be clamped with a simple constitution. Therefore, number of components can be reduced to decrease in size the apparatus.

Filed: 1984-08-28
Abstract: PURPOSE:To prevent mis-input due to detour by applying processing in response to the closing state of plural key switches except the detour when the simultaneous closing state of plural key switches is detected. CONSTITUTION:When plural switches are depressed at the same time and plural switches in a Y line are closed, that is, switches SW1n, SW2n connected to X1, X2 lines are closed. An encoder 2 detects it to check the detour, the Y line except Yn is selected sequentially to input the switch state to all X lines. When the closing state is not identical to select the Yn line, since no detour is generated and its input is made effective. On the other hand, when the state is identical, it is discriminated as occurrence of detour, the discrimination is intermitted and the keyboard processing is executed again from the initial state. When it is discriminated that there is a detour only once, no code conversion is attained.
