定の文字を印字する。The switch 4 is an on / off switch for switching the clock function and the printer function, and outputs an on / off signal to the control circuit 16
The control circuit 16 controls the entire circuit. When the switch 4 gives the ON signal 4a, the control circuit 16 outputs the ON signal from the OUT terminal based on the ON signal. The drive signal 9a is output to the detection unit 9. This drive signal 9a opens the gate of the transistor 18 via the resistor 17, lights the light emitting element 12, and irradiates the outer peripheral surface of the guide roller 7a with light. The reflected light of the light applied to the guide roller 7a is received by the light receiving element 13 of the detection unit 9,
It is given to the amplifier / detection unit 19 as a signal of waveform A modulated as shown in FIG. 4 (A) according to the monochrome display of the outer peripheral surface of the guide roller 7a and the rotation speed of the guide roller 7a. The signal given to the amplifier / detection unit 19 is amplified and detected here, and the upper and lower parts of the waveform A are cut by the roll pass filter (L, P, F) 20 as shown in FIG. 4 (B). The waveform B of the intermediate portion is sent to the waveform shaping circuit 21, shaped into a rectangular wave C as shown in FIG. 4 (C) by the waveform shaping circuit 21, and input to the IN terminal of the control circuit 16 as a detection signal. When the detection signal is input in this way, the control circuit 16 gives a clock pulse, a read / write signal and an address signal to the RAM 22, exchanges data with the RAM 22, and at the same time sends the address signal and the waveform shaping to the character generator ROM 23. A clock pulse (shown in FIG. 4D) D corresponding to the rising edge of the rectangular wave C shaped by the circuit 21 is output. Therefore, this clock pulse D is
The pulse width varies depending on the rotation speed of 7a, that is, the drawing speed of the recording paper 6, and the interval is narrow when the speed is fast and wide when the speed is slow. The character generator ROM23 is an address signal and the clock pulses D from the control circuit 16, creates the print data E, to output the result to the driver 24, the print data E, as shown in FIG. 5, E 0 ~ It consists of a pulse signal of E 6 and emits a predetermined pulse for each address according to the clock pulse D. Every 6 pulses of the clock pulse D constitutes one character. There is a space between the 7th and 7th shot. When the driver 24 is supplied with the print data E and the drive signal 24a from the control circuit 16, the driver 24 sends the drive signals 14a ... According to the pulse signals E 0 to E 6 of the print data E to the print head 14, and the print head 14 is driven. To drive. As a result, the print head 14 prints a predetermined character according to the drawing speed of the recording paper 6.

および表示切替を行なうようになっている。The control circuit 16 is constantly provided with the reference clock signal of a predetermined frequency generated by the oscillation circuit 25 after being divided by the frequency dividing circuit 26, and based on this, the time information is output when the switch 4 is off. While outputting and displaying the time on the display unit 2, when a predetermined signal is given from the switch unit 27 for time correction, display switching, etc., the time correction and display switching of the display unit 2 are performed accordingly. ing.

May be drawn through the printer 3.
If it does in this way, it will become more compact.

な印字ができる。As described above, according to the printer of the present invention, the recording paper is pulled out by the pulling-out operation from the outside, and the rotating body rotates while contacting the surface of the recording paper according to the pulling-out speed of the recording paper. Rotation of the rotating body by irradiating the outer peripheral surface with linear black and white display parts alternately in the axial direction of the body with light by the light emitting element of the detecting means and receiving the reflected light by the light receiving element of the detecting means. The speed is detected by the detection means, and the printing means prints on the recording paper at a speed corresponding to the rotation speed detected by the detection means.
Since it is not necessary to incorporate a drive source such as a motor for feeding the recording paper, the power consumption is low, the size is small and the structure is simple, and normal printing can be performed even if the drawing speed of the recording paper is irregular.
