Description

The present invention relates to a fixture for mounting and supporting a wireless display, and more particularly, a wireless display fixture having a power feeding mechanism for supplying power to a wireless display to be attached in a contactless manner and a wireless display using the same. About the system .

In a warehouse such as a distribution center, an operation for sorting a wide variety of articles to be delivered is performed for each delivery destination. Articles are displayed on a shelf, and a wireless display capable of wireless communication is provided on the shelf in association with each item.
For example, when picking instruction data is transmitted from the management device to a corresponding wireless display, the quantity to be picked is displayed on the display unit of the wireless display. The worker performs the picking work according to the quantity displayed on the display unit.
By the way, the wireless display is generally a charge type equipped with a battery. After driving for a predetermined time, the wireless display is once removed from the shelf for charging, and after charging, the wireless display is attached to the shelf for use. Therefore, the mounting position can be freely changed even when the shelf layout is changed, but there is a problem that it takes time to manage charging.

Thus, recently, an attempt has been made to attach a wireless display to a rail-shaped fixture and supply power to the wireless display in a non-contact manner (see, for example, Patent Document 1). According to this method, since the electric power can be supplied to the wireless display device in a non-contact manner, the wireless display device can be arranged at an arbitrary position as in the above-described charging type. However, since the wireless display is usually arranged on a multi-stage shelf such as a warehouse, a large number of rail-like fixtures are required for each stage. And the power supply line for supplying electric power to the wireless display attached to each fixture in a non-contact manner is extended and wired over the fixtures at each stage.
Therefore, when the shelf position and the number of steps are changed due to the store layout change, the power supply line is continuous, so the power supply line must be rewired in response to the layout change. There is a problem that operations such as reducing the number of installations or changing the installation position cannot be performed quickly.
