Title: Sheet cutting device and recorder using the device
Inventor: ISHIDA YASUSHI
IPC: B26D1/30
Filed: 1990-06-18
Abstract: PURPOSE:To prevent a finger, etc., from being inserted into the gap between a rocking edge and sheet discharging means, by projecting a support member which supports a fixed edge to the downstream side in the sheet transfer direction and covering this gap. CONSTITUTION:A lever 7d4 of a fixed edge stay 7d covers the gap beta between a rocking edge 7b and discharging roller shaft 8b2 at the friction completion side. Accordingly, the insertion of a finger, etc., between the lever 7d4 and discharging roller 8a becomes impossible. As a result, the danger of inserting a finger, etc., in the gap beta is eliminated even in the case of the gap between the rocking edge 7b and discharging roller shaft 8b2 at the friction completion side being set wider.

Title: Light-output stabilizing circuit
Inventor: SANADA TAKESHI
IPC: H04B10/00
Filed: 1985-07-19
Abstract: PURPOSE:To make a light emitting output and a peak output constant, by providing a bias-current controlling circuit, which makes the light output approximately constant, and a mark-rate detecting circuit for a digital signal, and correcting the output of the bias-current controlling circuit by utilizing the detected output of the mark-rate detecting circuit. CONSTITUTION:A mark-rate detecting circuit 6 dtects a '1' included in an input digital signal (a), i.e., a mark rate and adds the rate to an amplifier 7. The amplifier 7 outputs a low or high current in accordance with the high or low mark rate, which is detected by the mark-rate detecting circuit 6. The current is added to a bias-current controlling circuit 5. Meanwhile, a circuit comprising parts 1-5 forms a low current, which reduces the light output of the laser diode 1 when the output of the PD 3 becomes high by using the controlling circuit 5. The controlling circuit 5 generates a bias current by adding the current from an amplifier 4 and the current from the amplifier 7. Thus the laser diode 1 is biased. In this way, the light output can be stably supplied without using the mark rate, and the peak light output can be maintained constant.
