本発明は、カメラのデータ写し込み装置に関

発生となる。 With conventional data imprinting devices, a light-emitting diode is installed as a method for checking from outside the camera whether or not an imprinting command has been input from the camera body, and the light-emitting diode lights up at the same time as the input, thereby confirming that the imprint command has been input. A function to represent it was added. This function is especially essential for data imprinting devices in which imprinting commands are manually input. However, in this conventional method, the light emitting diode is provided without direct connection to the imprinting function, resulting in high cost, and a considerable amount of power is consumed when the light emitting diode is turned on, which hinders the reduction in power consumption. Furthermore, when using a small silver battery or lithium battery as a power source for an imprinting device, this type of battery has a relatively high internal resistance, so if it drives a load that consumes a relatively large amount of current, such as a light emitting diode, the power supply will The voltage decreases, resulting in device defects such as insufficient amount of imaged light.

器８が、一定時間光源５を点灯させる。 FIG. 1 shows a conventional embodiment in which the above drawbacks have been eliminated. The imprinting method of the data imprinting device in this example is to display the imprint data in a white outline on a liquid crystal display, turn on an imprint light source such as a lamp, and transmit the light through the liquid crystal display. By doing so, it becomes data-shaped light, which is then imprinted on film. 1 is a power source for the device, and a lithium battery or a silver battery is used. Reference numeral 2 denotes a data generator for forming imprint data information, and in particular, when the data is the calendar or time on the day of photographing, it consists of a clock device. Reference numeral 3 denotes a data driver that drives the imprinting display 4 made of a liquid crystal display based on the data information from the data generator 2. Reference numeral 5 denotes a light source for data imprinting, which is mainly a small lamp, and a light source driver 8 turns on the light source 5 for a certain period of time based on an imprinting command 7 from the camera side or manually.
また該装置では、写し込みデータをカメラ外部

部表示器９が設けられる。該表示器も液晶表示体
で構成され、同じデータ駆動器３で駆動される。 Furthermore, in this apparatus, an external display 9 is provided so that the imprint data can be displayed and monitored outside the camera. The display is also composed of a liquid crystal display and is driven by the same data driver 3.
また、写し込み命令７は、同時にマーク駆動器
１０へ送られ、後述する外部表示器９に設けられ
た写し込みマーク表示部を、写し込み命令の入力
後一定期間表示状態にする駆動信号が作られる。 The imprinting command 7 is also sent to the mark driver 10 at the same time, and a drive signal is generated that causes the imprinting mark display section provided on the external display 9, which will be described later, to be in a display state for a certain period of time after inputting the imprinting command. It will be done.
第２図に、外部表示器の表示例を示す。該例

２，１３がその年月日を表わす。１４は前述した
写し込みマークである。 FIG. 2 shows an example of the display on the external display. In this example, the imprint data is year, month, and day, and 11,1
2 and 13 represent the year, month, and day. 14 is the imprint mark mentioned above.
この様に、外部表示体に、写し込み命令と同期

に対する負担影響もおよぼさない。 In this way, if a mark is provided on the external display that is displayed in synchronization with the imprint command, input can be confirmed. In this device, since the imprint mark is formed on an external display made of a liquid crystal display, there is no cost burden as in the case of conventional light emitting diodes. Also, most of the circuit parts of this device are C-
Since it is configured using MOS on the same IC chip, the mark driver can also be configured within the same IC, and there is no burden on the circuit. Furthermore, since the input confirmation is displayed on the liquid crystal display, almost no power is consumed, and there is no burden on the power supply as in the conventional example.

データが入つているかどうかで確認するしかな
い。 However, in the example shown in FIG. 1, since the imprint mark is displayed when an imprint command is input, it only serves as an input confirmation and does not serve as a proper imprint confirmation. That is, even if the lamp of the imprint light source becomes defective and cannot emit light, it cannot be recognized from outside the camera. The only way to check is to open the back of the camera and check whether the imprint indicator lights up in response to the imprint command, or check to see if the data is included in the photo you have taken.

We provide a camera data imprinting device with a simple structure that allows input confirmation or imprint confirmation, and also has a function to display to the outside of the camera that the imprint light source is defective and does not light up and cannot be imprinted. The object of the present invention is to provide a data imprinting device for a camera having a camera.

ンプの様な大きな電流を消費する負荷をつけた場
合、電圧が低下する点に着目したことにある。 The example in FIG. 3 has a structure that eliminates this drawback. The characteristics of this example are that the liquid crystal display has a display voltage threshold, and because this type of power supply is a small battery, the voltage will drop when a load that consumes a large amount of current, such as a lamp, is attached. This is because we focused on the point of

値以下であれば非表示状態となる。 As is generally known, the structure of a liquid crystal display is such that a liquid crystal is interposed between two electrodes, a segment electrode and a common electrode, and when an electric field is applied to the electrodes, the liquid crystal undergoes an optical change and a desired display is obtained. . The signal applied to the electrodes is an alternating current signal, and if the effective voltage is equal to or higher than the threshold of the liquid crystal, the display is in the display state, and if it is lower than the threshold, the display is in the non-display state.

This is a circuit section including a lighting signal generation section of a part of a data driver and a light source driver. 17 is a light source, and 18 is a transistor of a light source driver. 19 is power supply 1
5 and the circuit section 16, and is normally in a closed state, and is in an open state while the light source 17 is turned on. This is a configuration to prevent the circuit section from malfunctioning due to a drop in the voltage of the power supply when the light source 17 is turned on. While the switch 19 is in the open state, the circuit section 16 is backed up by the charge stored in the capacitor 20. Ru. 21 is a mark driver for driving an imprint mark 22a for imprint confirmation provided on the external display 22;
Power supply 15 becomes a DC power supply. The external display 22 is a liquid crystal display, and as described above, the mark driver 21

Data display unit 2 driven by the data driver in 6
It has 2b. Note that the imprint mark 22a is
Unlike the example in FIG. 1, it is always in a display state. With this configuration, during normal imprinting, the drive voltage of the imprint mark will decrease as the power supply voltage decreases, and the setting should be made so that the voltage at that time is below the threshold of the liquid crystal. , the imprint mark is hidden, and the input can be confirmed in the above example. Furthermore, if the light source is defective and does not turn on, the voltage of the power supply will not drop because no large current will flow.
The imprint mark remains displayed and does not become hidden. Therefore, you can also check the imprint.

With this configuration, errors in data imprinting can be detected at an early stage, and costs can be reduced, and the convenience of use for photographers can be increased.
