Abstract: PROBLEM TO BE SOLVED: To prevent paper sheets from being left out in a paper sheet ejecting port by arranging the paper sheet ejecting port in the vicinity of a card ejecting port so as to simultaneously grasp a card and a paper sheet and collecting paper sheets left out in the paper sheet ejecting port. SOLUTION: A paper ejecting device provided in a card dealing device includes a paper ejecting port 10 in the lower side of a card ejecting port 9, and a paper sheet such as a receipt is ejected by being superposed on a card. For issuing this receipt, when a paper sheet is detected by a paper sheet sensor 76, a motor is rotated until no paper sheets are detected, and a receiver is ready to receive a paper sheet. Then, after the passage of fixed time, the motor is reversibly rotated and, when the paper sheet sensor 76 detects no paper sheets, this control is finished determining the receiving of the paper sheet by the receiver. But when the paper sheet sensor 76 detects a paper sheet, by determining non-receiving of the paper sheet by the receiver, the motor is reversibly rotated for another fixed time and then the paper sheet is collected.

Title: Method for measuring skew distortion of magnetic recording medium and its measuring instrument
Inventor: KISODA AKIRA
IPC: G11B20/02
Filed: 1990-07-17
Abstract: PURPOSE:To measure a skew distortion accurately by taking horizontal synchronization of a composite video signal inputted from an input terminal, regulating an external synchronizing signal frequency and obtaining skew distortion from a deviation between the frequency of the external synchronizing signal and a reference synchronizing signal frequency. CONSTITUTION:A variable frequency synchronizing signal generator and a monitor having a video input terminal and an external synchronizing signal input terminal are connected to measure skew distortion. In this case, since an external synchronizing signal is inputted, distortion is immediately observed on a screen and a pattern is easily displayed on the screen by regulating the synchronizing signal frequency. The skew distortion is obtained from a difference between the synchronizing signal frequency and the reference synchronizing signal frequency. The skew is accurately obtained by having only to display a pattern on the screen normally. Even when skew distortion is too excessive, the measurement is easily implemented by adopting the measuring method.

Filed: 1981-11-27
Abstract: PURPOSE:To facilitate the operation of a copying machine which allows copying operation during the forward and backward movement of an original scanning system respectively, by returning the scanning system to its starting position for an odd-numbered copy after copying operation ends. CONSTITUTION:Copying operation is carried out even during the backward movement of a platen 4 by changing directions of reflection of a light beam through the switching of mirror 9, or by switching a lens 30 and a lens array 33 with a shutter 34, thus obtaining a copy of an erect image. After a copy of an odd-number of sheets is taken, the platen 4 is at a forward movement ending position 3. If copying operation is restarted in said state, variation in scanning distance due to magnification variation or trouble in specifying a paper discharge direction through a sorter may occur. For this purpose, the platen 4 is returned to a starting position and consequently, a scan starts at the starting position when copying operation is restarted.
