Abstract

A screen reflects projection light for display. The screen has a screen base designed to be wound and including a first surface (front surface) and a second surface (rear surface) on the side opposite to the front surface. The front surface contains a display area that has a reflection film on which the projection light is reflected. The screen further has a flexible protection member which is disposed on the portion of the rear surface corresponding to the outside of the display area in the width direction of the display area, and extends through substantially the full length of the display area in the winding direction of the display area. The front surface is positioned outside when the screen base is wound.

Description

Technical field

[0001] The invention relates to a screen and a screen device. Background technique

[0002] Conventionally, there has been known a screen device that uses a screen to reflect projection light projected from a projection display device such as a projector to display an image. Patent Document 1 discloses the following: at both ends of the direction orthogonal to the direction in which the screen main body part and the non-screen main body part are joined and arranged on the back side of the screen, the first end and the second end are not connected to each other. Where the joined regions overlap, a first winding step prevention member and a second winding step prevention member are installed. Thereby, it is possible to provide a screen that can be wound and stored without the striped winding steps generated on the screen due to the step difference of the joint portion between the screen main body and the non-screen main body, and It has good flatness when used.

Embodiment approach

[0036] figure 1 It is a diagram schematically showing the screen device 1 according to the embodiment. Reference figure 1 The schematic structure of the screen device 1 of this embodiment will be briefly described.

[0037] The screen device 1 of this embodiment is a reflective screen device 1 and is a type of device that is installed on the ground or the like and used. In the screen device 1, a substantially rectangular screen is drawn upward (in a direction substantially perpendicular to the ground) from the inside of the box-shaped housing 7 formed in a rectangular parallelepiped shape by the operation of the retractable mechanism part 4 and the winding mechanism part 5 2. The screen 2 stands up with respect to the ground and becomes a usable state. Furthermore, the screen 2 reflects the projection light L emitted from the projector 6 provided in the housing 7 toward the viewer. In addition, the details of the screen device 1 will be described later.
