Abstract

PURPOSE:To prevent unsightly photographing due to transfer in an incomplete state by raising an alarm when a transfer module is not detained. CONSTITUTION:If the transfer module is detained though a camera is laid down or set vertically, a detaining pawl of a rear cover is not dropped into a groove of the transfer module but is shaked in a prescribed direction to turn on a switch 52. Then, a closed circuit is formed with a battery 9, and an alarm is raised by lighting of an LED57. As the result, unsightly photographing due to transfer in the incomplete state is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data imprinting device for a camera.

The data imprinting module is rotated υ by external operation in response to horizontal and vertical shooting, so that data is always imprinted on short positions such as the F part of both images. was previously proposed by the applicant.

In such cameras, the imprint module should be rotated at 90°.
As it rotates, it locks in the positions corresponding to horizontal and vertical shooting, but if you take a photo without the imprint module in this locking position, the data will be transferred to the image frame. On the other hand, it may be extremely unsightly, such as being skewed or imperfectly printed, which can ruin a well-earned photo.

The present invention aims to solve the above-mentioned drawbacks, and is configured to issue a warning when the imprinting module is not in the locked position, informing the photographer that the position of the imprinting module should be corrected. This allows failure to be prevented in advance.

In the above configuration, when photographing is to be carried out with the camera held in a horizontal position, the imprint module 3 is placed in the state shown in FIG. 3.

At this time, the tip 50a of the locking lever 50 falls into the notch 21d on the side surface of the lid 21 and locks the module 3, and the tail end 50b pushes one contact piece 52a of the switch 52 to turn off the switch 52. The LED will not emit light. When the back cover is closed, the switch SW1. S
Since both W2 are on, when the shutter is released, a trigger signal is sent from the circuit 103 of the camera body (1111) to the trigger signal input section IRIi of the IC102.
n, and is input to the trigger signal output section TRI. An imprint start signal is input to one side of the AND gate 104 from ut.

Since the switch 52 is in the off state, a high signal is input to the other AND gate, so the output of the AND gate also becomes high, and the transistor Tr is turned on. Lamp 25. A closed circuit consisting of the transistor Tr is formed, and the lamp 25 is lit for a certain period of time determined by the IC 102. The light from the lamp 25 is reflected by the mirror 26, passes through the liquid crystal display 27, passes through the elongated hole 13a of the pressure plate, reaches the film, and is displayed on the display 27 at the bottom of the screen as shown in FIG. Data such as the year, month, day, hour, minute, and second are imprinted. When photographing is to be carried out in the vertical position, the imprint module 3 is brought into the state shown in FIG. 4 by placing a finger on the knurling 33 or the finger hook 32 and turning it 90 degrees counterclockwise from the position shown in FIG. 3. At the beginning of the rotation of the module 3, the tip 50a of the locking pawl 50 crosses over the notch 21c and comes into contact with the side surface of the lid 21. At this time, the locking pawl 50 is turned counterclockwise against the spring 51, so that the suppression of the switch contact piece 52a by the tail end 50e is released.
The contact piece 52a returns by its own elasticity and comes into contact with the contact piece 52b,
Switch 52 is turned on. Therefore, in FIG. 10, battery 9, LED 57. A closed circuit consisting of resistor R7 is formed and the LED lights up. The state until the module 3 reaches the state shown in Figure 4 continues, so if rotation is stopped midway, the LED light will be visible from the hole in the back cover as shown in Figure 5. In this state, even if the shutter is released, a low signal is input to the other side of the AND gate via the inverter 105, so the transistor is Since the Tr is not turned on and the lamp 25 is not lit, no data is imprinted.

When the imprint module is further turned, the tip 50 of the locking claw 50
a sinks into the notch groove 21cKg and presses the contact piece 52a again with its tail end 50b, so the switch 52 is turned off and LP2
D57 goes out.

When the shutter is released in this state, the lamp 25 lights up in the same way as in the case of horizontal position photography, and the data is imprinted at the position shown in FIG. It will be done.

In the above embodiment, when the imprinting module 3 is not in the locking position, the LED is lit to display a warning on the outside of the camera to give a warning, but in FIG. An example will be shown in which notification is made.

In the figure, 107 is a sounding body, 108 is an oscillator, 106 is an AND gate, &~R, and the other parts are the same as in FIG. 10, so a description thereof will be omitted.

In this configuration, when the imprinting module 3 is locked at the imprinting position corresponding to horizontal or vertical shooting,
That is, when the switch 52 is off, the AND gate 1
No. 04 is connected to one terminal through an inverter 105.
Since the A signal is manually input, the circuit 10 on the camera body side
When a NO signal is input from the trigger output section TRIout of the IC 102 to the other terminal of the AND gate by the trigger signal from the IC 102, the transistor Tr is turned on, and the lithium 'Kameike'9, the lamp 25, and the transistor 'Pr' are turned on.
A closed circuit is formed, and the rung 25 emits light for a certain period of time determined by the IC 102 to imprint data. Since the 0 switch 52 is in the OFF position, the sounding element 1 (J7 does not operate. When the integrated module 3 is not in the locked position, the switch 52 is in the on state, so
A high signal is input to the upper terminal of the AND gate 106, and a high signal is input from the oscillator 108 to the other terminal, so the transistor Tr is turned on, and the lithium battery 9,
A closed circuit consisting of the switch 52, the sounding body 107, and the transistor lrr is formed, and the sounding body 107 is activated to emit a clearing sound. At this time, the low signal is input to the lower terminal of the AND gate 104 via the inverter 105, so the trigger signal from the camera body is input to the I
C102 trigger output section TRI. Even if the signal (from ut) is input to the terminal above the AND gate, the transistor Tr is not turned on and the lamp 25 is not lit.

In all of the above embodiments, imprinting is also prohibited while the warning means, such as the LED or the sounding body, is in operation, but the present invention is not limited to this, and it is also possible to issue only a warning. Of course, this is possible, and the warning means is not limited to LEDs or sounding bodies.

As described above, the present invention provides a data imprinting device that locks an imprinting module at an imprinting position corresponding to a horizontal position and an imprinting position corresponding to a vertical position and imprints data at each suitable position. A switch is provided to identify when the module is in a position other than the locking position mentioned above, and is configured to alert the outside world, completely preventing data from being imprinted in an incomplete state due to the photographer's carelessness. be able to.
