Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to the structure of a wireless barcode reader.

<Prior Art> Recent cooking appliances, especially microwave ovens, have become multifunctional with the spread of microcomputers and sensors, and many keys are arranged on the operation panel. For example, there are various menu keys for automatic heating, microwave high/medium/low, grill, convection keys, etc. for manual heating. It is very troublesome for the user to operate these keys and make settings (heating time and temperature) according to each menu, and it is easy to make erroneous operations and settings, and the usability is poor.

Therefore, information such as heating time, heating temperature, heating output, sensor detection level, etc. for each heating stage is printed in a barcode on the cooking book that comes with the microwave oven, and the user can read the barcode print with a barcode reader. For example, a convenient microwave oven has been proposed that allows settings to be made according to the cooking menu.

However, if the barcode reader and the microwave oven body are wired, the barcode reader has the disadvantage of poor usability, so wirelessization is being considered, but various considerations have been raised in the wirelessization.

<Purpose> This invention addresses the above-mentioned issues of the wireless barcode reader, which is equipped with a reading section for reading barcodes at one end and a transmitting section for transmitting the read barcode signal to the main body of the device at the other end. The purpose of this invention is to set a rational orientation direction of the transmitting section with respect to the reading section.

<Example> An example of the present invention will be described below with reference to the drawings.

Figure 1 is a schematic explanatory diagram of a microwave oven that employs the wireless barcode reader of the present invention, Figure 2 is an electrical circuit diagram of the wireless barcode reader, and Figure 3 is a schematic diagram of a microwave oven that uses the wireless barcode reader of the present invention.
The figure is an electrical circuit diagram of the microwave oven main unit related to the wireless barcode reader, Figure 4 is a front view of the operation panel of the microwave oven main unit related to the wireless barcode reader, and Figure 5 a, b, and c are the main They are a front view, a right side view, and a bottom view of the invented wireless barcode reader.

The wireless barcode reader 1 of the present invention reads the barcode 2a printed on the cooking book 2,
It has the function of wirelessly transmitting the read information to the microwave oven main body 3.

The wireless barcode reader 1 includes a reading section 3 that illuminates the barcode 2a with light from a light emitting diode 3a and receives the reflected light with a light receiving diode 3b to read the barcode 2a, and a transmitter that transmits the read barcode information by infrared rays. 4, a control circuit section 5 for controlling them, a secondary battery 6 for power supply, and a charging jack 7 for charging the secondary battery 6. wireless barcode reader 1
The reason why the secondary battery 6 was adopted as the power source is that a large current is required to make the infrared light emitting diode 4 emit light, and the microwave bar code has a large amount of information, so a large current must be applied for a long period of time. Battery consumption is severe. Therefore, the purpose is to reduce the burden on the user as much as possible.

As shown in FIG. 4, the operation panel 8 of the microwave oven main body 3 has a reader storage section 9 that stores the wireless barcode reader 1 and a receiving section 10 that receives the barcode signal transmitted from the reader 1. It is provided near the pipe 11. A charging plug 12 is disposed in the innermost part of the reader storage section 9 and is connected to the charging jack 7 of the reader 1 when the reader 1 is inserted and stored.The charging plug 12 is connected to the charging circuit 13. It is connected.

Further, the receiving section 10 includes a photodiode 10a that receives infrared rays from the reader 1 and a light receiving circuit 10.
b, and outputs the received barcode signal to the control circuit 14. The control circuit 14 controls the microwave heating device 15, the heater 16, etc. based on a heating program input from the receiving section 10.

In the present invention, the reading section 3 of the reader 1 and the charging jack 7 are disposed on one side as shown in FIG. It stands out a little more. Further, in the transmitting section 4 on the other side, an infrared light emitting diode 21 as a first transmitter and an infrared light emitting diode 22 as a second transmitter are disposed in directions orthogonal to each other, and a filter 17 Covered. Therefore, when the reader 1 is inserted and stored in the reader storage section 9, only the filter 17 is visible. The direction of orientation of the infrared light emitting diode 21 is made perpendicular to the direction of orientation of the reading section 3. The reason for this is that when reading the barcode 2a of the cookbook 2, it is best to place the cookbook 2 on a desk or in your hand, with the barcode printed surface parallel to the ground, and hold the reader 1 vertically. Generally speaking, the microwave oven body 3 is also placed perpendicular to the ground, so in order to efficiently transmit data to the receiver 10 using the infrared light emitting diode 4, which has a 40% reduction in output and has a transmission direction of approximately ±30°, it is necessary to This is because it is necessary to transmit substantially perpendicularly, that is, substantially perpendicularly to the orientation direction of the reading unit 3.

Also, the reason why the direction of infrared light emitting diode 22 is made parallel to the direction of direction of reading section 3 is to enable remote control operations such as starting and stopping heating, which will be described later, to be performed with a natural grip. This is because of consideration.

Barcode reading key 1 is located at the bottom of reader 1.
8 is disposed, and a stop/cancel key 19 and a heating key 20, which are remote control operating sections, are disposed on the top of the reader 1 at a height of 3 cm or more from the reading section 3.

The reason why the stop/cancel key 19 and the heating key 20 are provided on the top of the reader 1 and at a height of 3 cm or more is that when you hold the reader 1 in your hand and trace the barcode 2a on the cookbook 2, you can stop/cancel the food. This is to prevent unexpected erroneous operations caused by touching the heating key 19 or the heating key 20 unconsciously. This stop/
The cancel key 19 and the heating key 20 are essential functions for a microwave oven, and are essential for using the reader 1 as a remote control.

Next, the operation of the reader 1 will be explained. Pull out the wireless barcode reader 1 from the microwave oven body 3, hold it in your hand, press the barcode reading key 18, and trace the barcode 2a on the cooking book 2 to read it. When the heating key 20 is pressed, the microwave oven controls the microwave heating device 15, heater 16, etc. to start heating. If you want to stop heating midway through, press the stop/cancel key 19 and the control circuit will turn off the microwave heating device 15, heater 16, etc.

Therefore, the user can easily and reliably make input settings corresponding to the menu simply by tracing the barcode on the cookbook 2, and can also start or stop heating or cancel input settings by simply tracing the barcode on the cookbook 2. It is very convenient and easy to use because it can be done without having to go to the store.

In the above embodiment, since there is only one infrared light emitting diode 4, the directivity in the circumferential direction is narrow.
By arranging an appropriate number of diodes at equal intervals in the circumferential direction, it is possible to emit light all around the circumference, and if the infrared light emitting diode 4 of the above embodiment is rotatable, the grip of the same reader 1 can be You can send the signal in the circumferential direction of your choice.

<Effects> Since the wireless barcode reader of the present invention has the above-mentioned configuration, it is possible to efficiently transmit the read barcode signal as it is to the main body of the device while reading the barcode in the reading section, and the read barcode There is no need for a storage unit that temporarily stores signals, and the number of parts can be reduced, making it possible to downsize the wireless barcode reader and reduce power consumption.

In addition, the remote control for starting and stopping heating can be operated with a natural grip, and the usability of the wireless barcode reader can be improved.
